Bleach Bypass on HDV

I've been trying out various Bleach Bypass techniques on 60i and 24p footage. It appears source matters a lot. HDV is 4:2:0 while DV is 4:1:1 for NTSC. It appears that DV with its compressed colors is easier to bleach using color curves, saturation, and color overlay. HDV, at least the color rich kind made by the HV20, needs to be desaturated to as low as 20% on the bottom layer. Sometimes it even helps to give a color tinge to the entire clip too. More experimentation to be done!
